Math Must Read Mentor Texts Linky {Estimation}

I'm excited to share another Must Read Mentor Text with you. This week's topic is Math, and I can't wait to see all of your books you link up! :)

The book I've chosen is Betcha! by Stuart J. Murphy

Amazon.com Book Description: What do cars, toys, people, and jelly beans have in common? They can all be estimated. Two friends try out their estimating skills and find out that estimating can have real rewards––especially when there’s a contest to enter!

I just found this book a few days ago, and I'm really happy that I did. One of the skills that students always struggle with is estimation. Sometimes they have trouble with rounding numbers, and other times they just forget how to estimate. This book does an awesome job of showing students real world examples of estimation. It reminds us that we use estimation every day, and that estimation is a quick way to find a total. It also shows the importance of mental math.

As I read the book, I brainstormed ways I can use this with my students next year. I think that I am going to use this book to introduce my unit on estimation. I am going to give each of my students a whiteboard and marker. They are going to solve the problems in the story as the kids in the story do. I will use my document camera to show the illustrations so that they can see them up close.

The format of the book has one friend asking the other friend to find a total. On this page, he is asking for the total number of people on the bus.

The other friend then uses mental math to estimate the total. In this example, he uses multiplication to estimate. (Before showing the students this page I would ask them how they could find the total number of people on the bus. Then, I would have them try to find the answer on their whiteboards.)

On this page, the boy is finding the total of all the items in a store window. I love that it uses a real world example with money!

After reading this book, I will take the students around the school and we will try doing some real life activities- estimating cars in the parking lot, chairs in a classroom, seats in the cafeteria, etc. I think the students will enjoy it, and they will practice their mental math and estimation skills!

Do you have any mental math or estimation activities that you love doing?

Please link up your Math Mentor Texts! :)

My fourth graders have difficulty every year with estimation. I love that you will include real life estimation after reading. This will truly the students grasp the concept. I will be using this in my classroom. Thank you for sharing!

Love it! I really like how it shows real world estimating and the fact that sometimes we can get an estimate on some things versus needing an actual total.Love the idea of an estimation walk around the school!Linking up later...heading home in a bit...at a stay-cation resort!Fabulous Fifth Grade Fun
